To all (whom 'it may conca/vt Be it known that I. HARRY L. T UnNrY,

a citizen of the `United States, yresidingr at lortland, in the county of Multnomah and 5 State of Oregon, have invented neuI and useful Im irovernents in Loggingdingincs. of which t lel following is a specification.

It is desirable inlogging engines to have the main drum so arranged that it can he driven at two speeds from the same drive shaft. This is particularly true where there are other drums driven from this drive shaft because the secondary drums` should he driven ordnaril \v at their maximum speeds at all timcs. 1t is also desirable that the mechanism ma)r be such as to permit of the change of speed of the main drum while the drum is in motion. The Y'construction to accomplish this purpose must be rugged because engines of this t pe are subjected to very severe use.

ith this invention the main drum is provided with varying speeds and the speed of the drum may be changed while immo tion. The mechanism .is rugged and of simple construction.

The invention is illustrated in the accompanying drawings as follower- Figure 1 shows a plan view, partly 1n section, of the engine.

boiler 6. Engines 7 are mounted on the side beams. he engines operate on lthe cranks S and operate the drive shaft 9. The drive shaft 9 is mounted in bearings lOvmounted on the beams l, 2 and. 3.

A main drum 11' is journaled on a shaft 12. The shaft 12 .is journaled in beanings 13 in the beams 1 and 3. The drum is provided Witli a friction "surface 14 operating against the friction blocks 15 on the gear Wheel 16. A. friction operating pin 17A extends into thcend of the shaft 12 and, may beroperated by any friction actuating` mechanism desired. (not Shown). The

' The engine is provided Withthe usualV .platelti operates the drum and moves it axially on the shaft so as to move the friction surfaces into engagement. A spring lf) shifts the drum to move the friction sur faces out of engagement when the friction device operating on the pin t7 is released. rfliegggear wheel is locked ou the sha it 12 b v means of a li'ey 20. The gear wheel is provided witlran internal 22and a pinion 23 meshes with thc grat' E12. The iinion 23 is mounted on an intermediate shaft 24. The intermediate shaft is journalefsiu a bearing on the beam 3 and is supplied with a bunijnj! titi which is jourY naled in a bearing T of: thtl laam 2. tvars 28 and 2f) are journalcd ou the shaft zal and these i gears mesh with gears- 34) and 31 fixed on the drive shaft 9. The gear ratio of the gears 2S and 30 differs from the gear ratio oi the gears 29 and 3l, the gear 30 being larger than the gear 32 and drives the gear 28 at a higher Speed than the gear 29.y For convenience, therefore. the gears 28 and 30 are designated as the high speed gears.

A drivel' 32 .is locked on the shaft 24 by means of a key 33. t is protvided with opposing friction surfaces 34 and 35. Friction blocks 36 on the gear 28 operate on the friction surface 34 and blocks 37 on the gear 29 operate on the Vfriction surface A bushing 38 is arranged on the shaft 24 and Within the gear 28. This bushing is slidingly mounted on the shaft 24. It is provided with a shoulder 39 by means o f which pressure may be exerted on the gear .Q8-and consequently on the friction blocks 36. A washer 40 may be arranged between the shoulder 39 and the gear 28 if desiredm Asimilar bushing 41 is arranged on the shaft 24.within the gear 29 and is provided with a shoulder 42. The bushing 41 is slidingli mounted on the shaft 24 and the shoulder so engages the gear that vwhen 'pressure is exerted on the bushing the gear may be moved axially on the shaftso as to move the blocks 37 into engagement withv the friction surfaces 35. A washer 43 is provided between the shoulder and gear if desired.` Springs 44 are arranged to opertot ate on the gear 28 and move the friction blocks 34 out' of engagement when released. A spring 45 moves the friction blocks 37 out of engagement when the gear 29 is released. f

35 55. It will be readily Operating rods 46, preferably three of them, extend4 through the bushings 26, 38 and 41. These-rorls are provided with ad 'usting nuts 47 which engage the bushing 8 and are provided with heads 48 engaging the bushini.r 4l. It will be readily seen that when these rdds are moved in one direction they will move' the blocksl 37 into engagement with tlit friction surfaces 35, thus l throwing the low speed gear into engagement and when moved in the opposite direction they will release the low s peedfgea'r and operating through the bnshm 38 orco the blocks V36 into engagement wit the -friction surfaces 34, thus throwing the high speed into action. Both the high and low leed gears operate in the sanie directiongand communicate their motion through the rivm-to the vintermediates shaft and Ythis through the pinion 23 and gear 22 communicates the movement to the mainl drum. The clearance of the friction blocks may be adjusted by the nuts 47 on the rods 46.

I prefer to operate the rods through a fluidactuated friction device, the actuating fluid being ordinarily steam from the boiler. The end of the `shaft 24 is screw-threaded at 49 and a cylinder 50 is secured on this'screvw threaded end. The cylinder is provided S0 with a cover 50, A piston 51 operates in the cylinder. The rods 46 have the reduced ends 52 forming shoulders 53. `The reduced ends extend throu h the piston and are secured by nuts 54. he nods extend through glands seen that as the iston is moved in either direction the ro s are carried with thema so as ,to throw in the hi h or low speed gear train as desired. A tu 56 extends from the outer end of the cylinder. This tube has a head'57 Ywhich secures it within the inner surface of the cover 5il.` The outer end of the tube is secured in a head 58. A steam line 59 enters the head 58 and communicates with the tube 4s 56 so as to deliver steam to the outer end of the cylinder. The steam line is controlled by a valve (not shown). Any type of valve may be used and ordinarily may be placed in such `osilion as to be conveniently operated liy the operator. The

head 58 has an extension 60 forming an annular space 61 `outside of the tube 56; This extension 6() extends through a gland 62 and the annular space 6l communicates with 66 a port 63. the port leading to the opposite end of the cylinder from that to which thev tube 56 leads. A supply pipe 64leads into the head and delivers steam to the s ace 61.

A suitable valve (not shown)y is provided for the pipe 64 s well as the pi e 59 'so that steam may be admitted and ex austed from the sides of the piston so as` to move `the piston in either direction.

A seconder shaft is jonrnaled in a 86 bearing 66. gear 67 is fixed \on .the shaft` 65. Drums 68 and 69 are mounted on the shaft 65. A driver 70 is fixed on the shaft 65 by means of a ke 70, he driver has the friction blocks 7Y1 and 72 ada ted to enga re the friction surfaces 73 an 74 on 70 the( rums 68 and 69 respectively. A thrust pin 75 extends through the end of the shaft 65 and is operated. by any desirable friction device (not shown). It operates on a cross key 76, the crosskey operating on a collar 'I5 77. The collar 77 communicates movement by the pins 67? to a collar 67. at the end of the drum 68. By movingthe coll-ar 77 endwise the drum 68 is moved axially so as to throw the friction surface 73 into en age- 80 ment with-the block 71. spring 8 is provided for releasing the drum 68. A thrust pin 79 is arranged in the opposite end `of the shaft 65 from the pin ,75 and is v operated by any convenient friction device. It operates a cross key 8U. The cross key roperates on a collar 81 to move the drum 69. 'he movement of the drum 69 throws the :friction surface 74 into engagement with the block 72 when desired. A spring 82 90 releases the drum 69.

The drums 68 and 69 are designed to carry operating lines one of` which is the trip line. Thetrip line handles the main line, that is to say, carries out the main line after it has been wound in on the main drum drawing in` its load. inasmuch as this carrying out of the main line involves practica ly` the same load in each instance the trip line should'be run atea comparativelv- 100 high speed and at a uniform` speed. With the main line it is desirable to vary its speed, a slower speed being used to given greater power when the load requires it and to give a better control when conditions y make this slower speed desirable and to give the l i h speed where conditions will )ei-mit it auf the power of the engine is su cient to carry the load at such high speed. It will vloe readily seen as above described the main drum may be given two speeds and that the speel` of the drum may be changed Vwhile the machine is in motion and that this variation ofthe speed of the main drum does not alter the speed of the drums 68 116 and 69. i
